have 150+ hours flying and am looking to take my private check ride within a month
May I ask what the reason is for this somewhat unusual number of hours?
*Your medical has been revoked out of an abundance of caution. You should probably have had a SODA and they can’t go “hey he didn’t break anything yet he’s good to go”.
You’ll need to get your medical back and this will take a while. Probably one or two statements from specialists and submitting them to the FAA.
* You are not telling us everything. Who is “they” and why was it necessary to do a test now for them to discover something that you already knew about? In your first post you said you didn’t but in your second you said you did.
Did you know about this and ‘forgot’ to mention it on your initial medical application?
